Title: Metallic substance discriminating device
Inventor: TAKAMIZAWA KAIHEI
IPC: G01B7/00
Filed: 1991-02-28
Abstract: PURPOSE:To provide a metallic substance discriminating device having simple structure and excellent detection accuracy by relatively moving a metallic substance into the hollow of a coil in which lines of magnetic force are generated and detecting changes in the frequency and amplitude of an oscillation signal clue to the changes of coil impedance and inductance as the feature parameters of the metallic substance. CONSTITUTION:A circuit consisting of a comparator 30, capacitors C1, C2, a resistor Rf, and a coil 25 generates an AC signal S1 with frequency and amplitude determined by circuit constants. The frequency of the AC signal S1 is changed in accordance with the changes of inductance and impedance obtained when the metallic substance 21 passes lines of magnetic force generated in the coil 25. A frequency detecting circuit 32 outputs a rectangular signal Df with frequency equal to that of the signal S1 to an output terminal 33 and an envelope detecting circuit 34 outputs an envelope signal SL to an output terminal 35. Since the amplitude of the signal S1 and the frequency of the signal Df are changed in accordance with the material and cross-sectional area of the metallic substance 21, the shape and material of the metallic substance 21 can be specified by analyzing the changes.

Title: Fabry-perot type optical modulator
Inventor: NAKAMURA KUNIO
IPC: G02B5/00
Filed: 1982-03-08
Abstract: PURPOSE:To reduce the number of lead wires by holding the respective circumferential edge parts of two sheets of transparent flat plates with annular laminated piezoelectric elements, and disposing the respective laminated piezoelectric elements concentrically. CONSTITUTION:Transparent flat plates 11, 12 are fixed to a holding table 15 by means of annular laminated piezoelectric elements 13, 14 in the circumferential edge parts. The two elements 13, 14 are connected to each other electrically and are connected respectively to an electric power source 16. Electricity is applied to the elements 13, 14 in such a way as to fluctuate synchronously in opposite directions from each other when conducted thereto. Thus, the space between the parallel faces is the sum of the displacements of the respective planes and the degree of modulation increases eventually if the impressed voltage is the same and the laminated number of sheets is the same. The errors owing to the fluctuation in the thickness of the elements 13, 14 are offset to each other since both plates 11, 12 are mounted on the similar elements 13, 14, whereby the errors are made nearly zero.

IPC: F02P5/15
Filed: 1988-02-18
Abstract: PURPOSE:To satisfactorily execute the control of knocking-limit ignition timing in an ignition timing controller which has a simple logic by controlling the quantity of compensation for ignition timing corresponding to knocking on the basis of a bank. CONSTITUTION:Each of a plurality of cylinders in an internal combustion engine 1 has primary and secondary banks 1a and 1b separated from each other. In a micro-computer 4 the quantity of compensation for an ignition timing inside each of the banks, discriminated by a cylinder discriminating signal sent from an angle sensor 6 is changed or corrected to a higher or lower quantity of compensation for every bank on the basis of the knocking discriminated result obtained from knocking sensors 2 and 3. Using the reference ignition timing, the quantity of compensation for ignition timing except the compensation for knocking and the quantity of compensation for ignition timing for each bank, the final ignition timing is determined. The ignition timing of a cylinder inside a bank with the ignition timing phase in the delay position, as well as that of a cylinder inside a bank with the ignition timing phase in the advance position may be controlled satisfactorily.

Title: Molding method for coating in mold
Inventor: NAKATANI YOSHITAKA
IPC: B29K101/10
Filed: 1993-02-25
Abstract: PURPOSE:To prevent deviation of a horizontal balance between upper and lower molds by charging thermosetting molding material in the molds and maintaining a molding pressure constant up to the time of completing charging of a coating material. CONSTITUTION:A thermosetting molding material is charged under pressure of 10-60kg/cm<2> in a mold, heated-pressure molded. Thus, after a molding form base material made of the molding material becomes semicured, a coating material is cast while holding the molding pressure constant without altering it. Accordingly, the mold is scarcely inclined from an initially set state. Therefore, since the molding pressure is not applied irregularly to a specific surface, the coating material smoothly flows between the surface of the base material made of the molding material and the mold, and even if the base material having an abruptly oblique surface is used, a coating layer having excellent adhesive properties is formed on the oblique surface.
